我有一个带有很多单选按钮和几个文本字段的表单。所以......
<input type="radio" name="pic" id="pic" value="val1">
<input type="radio" name="pic" id="pic" value="val2">
<input type="radio" name="pic" id="pic" value="val3">
<input type="text" name="email" id="email" value="">
<input type="text" name="comment" id="comment" value="">
并且在打开灯箱的表单后面有一个链接。我希望仅在选中单选按钮并填写两个字段时才启用该链接。非常感谢你的帮助。

我认为这应该有效:
if ($('input:radio[name=pic]:checked').length && $('#email').val().length && $('#comment').val().length) {
/* activate the lightbox link */
}
else {
alert("Please ensure you've selected one of the radio buttons, and filled out the text-fields.");
}
<小时/> 已修改以修改您的代码:
<form action="#" method="post">
<input type="radio" name="pic" id="pic" value="val1">
<input type="radio" name="pic" id="pic" value="val2">
<input type="radio" name="pic" id="pic" value="val3">
<input type="text" name="email" id="email" value="">
<input type="text" name="comment" id="comment" value="">
<input type="submit" value="submit" />
</form>
$('form').submit(
function() {
if ($('input:radio[name=pic]:checked').length && $('#email').val().length && $('#comment').val().length) { /* activate the lightbox link */
}
else {
alert("Please ensure you've selected one of the radio buttons, and filled out the text-fields.");
}
return false;
});

$("#link").click(function(e) {
if ($('input[name=pic]:checked').val() && $('#email').val() && $('#comment').val()) lightbox();
else e.preventDefault();
});
答案 2 :(得分:0)
function checklink() {
if ($('[name=pic]').val()) && $('#email').val() && $('#comment').val()) {
$('#linkId').hide();
} else {
$('#linkId').show()
}
然后将onchange="checklink()"
添加到输入字段
